Experimental investigation of cavitation interaction between a pressure wave and a plate in a liquid
Abstract
The facility described was used to study the onset of cavitation in a liquid and the plastic deformation and fracture of plates. The facility is 3.5 m high and has a useful area of 4 sq m. The basic principle of operation is the conversion of the kinetic energy of a piston into a pressure wave incident on a deformable plate. The velocity of the piston can be varied in the range between 0.1 and 50 m/sec. Tests with Duralumin, aluminum, and other plates showed that cavitation has a strong effect on the interaction of a pressure wave (in liquid) and a plate. Fracture of clamped rectangular plates proceeds by bulging, followed by shearing off of the bulge with the shear lines roughly parallel to the edges of the plate. Fracture photographs are presented.
